LxVox (V1.0, 9K, 21-OCT-98)
is a very small (1700 bytes) WAV player running in 64KB on any
x86 computer. It plays 8 bit mono WAV files of any size and
supports any sampling rate. LxVox may also be used as a plug-in

LxMap (V3.0, 10K, 02-FEB-02)
is a small map viewer. It connects streets to locations in a
standard picture file. You select a street, and LxMap immediately

LxPro (V2.4, 22K, 18-JUN-02)
is a SideKick like TSR for HP Palmtops only.
It gives you complete control over all special HP Palmtop features.

a keycode window, a programmer's calculator window and an I/O port window.

LxCic (V2.1, 17K, 22-OCT-99)
is a I/O card enabler and thus a CIC100 alternative on
the Palmtop. LxCic may be used nonresident or resident. If
loaded resident, it only takes 1200 bytes of memory and may be
unloaded at any time. Currently supports modem and network cards.
Source code included.

Nodelay (V1.0, 2K, 23-NOV-01)
removes the delay of flash cards after power on.

Vanity (V1.0, 2K, 20-NOV-00)

SPHiNX C-- compiler. Source code is included.

PDU (V3.0, 6K, 20-JAN-02)
converts an ASCII short message (SMS) into a protocol data unit
(PDU) and vice versa. PDU format is required by some mobile phones
like the Siemens S25, C35i and S35i, but it also works with
Nokia phones. If you want to handle your SMS like email on the
HP200LX, you have to download Tony Hutchins
POSTPDU.

AutoCaps (V3.1, 4K, 28-JUL-00)
is a TSR which automatically changes the start of a new sentence
to upper case and also allows double click at the beginning of
a word to capitalize it's first letter. Runs on Palmtops and Desktops.

with batch files.

Minicom (V3.0, 2K, 09-MAR-99)
is a 700 byte communications program for COM1-COM4 allowing you
to do simple transfers and tests. It supports DOS redirection, hence it
can get it's input from a file and send it's output to a file.

Ring (V3.2, 3K, 16-NOV-99)
uses the Palmtop's hidden feature of detecting GSM signals.
If such signals are on the air, the program simply plays a ring sound.
It's DEBUG mode should help to find a shielding for the palmtop to
protect it from EMI (electromagnetic interference). EMI is a serious
problem if you want to use an infrared connection between the palmtop
and a mobile phone.

is an incredible graphics simulation of burning flames that is
only 370 bytes. It was ported from VGA to CGA using the Sphinx C--
